Background technique
In the cooling system and cold-heat exchange system of fuel power, need to adopt clip connected rubber pipeline, the general larger worm gear clamping hoop of chucking scope that adopts of tradition connects.But because the temperature variation of this system is larger, temperature is up to 150 ° of C even higher when equipment working state, northerly winter, low temperature can reach-50 ° of C, thereby the rubber pipe that connects occurs expanding with heat and contract with cold with difference variation, along with wearing out of sebific duct, the elasticity of sebific duct fades away, and the loosening of sebific duct occur immediately.Because the shortcoming of traditional worm gear clamping hoop is automatically to regulate fastening scope, the leakage of pipeline will appear when sebific duct is loosening, damage thereby affect the normal operation of equipment even power occurs, need to re-start secondary fastening.Because cooling system and cold-heat exchange system generally all are installed in the bottom of equipment, the fastening operating difficulties of secondary will carry out large dismounting to original equipment and just can finish, and workload is large, and maintenance cost is high.
Someone attempted using T-shaped clip with spring instead at cold-heat exchange system afterwards, substantially solved large pipeline leakage problem, but the shortcoming of the T-shaped clip of spring is also obviously more: 1, the chucking scope of the T-shaped clip of spring is that the length by T-shaped bolt decides, the T-shaped bolt of this structure can't be done oversizely, general 93mm, the diameter adjustment scope is substantially about 8mm, in the face of numerous calibers, just need to design a large amount of specifications and come corresponding connecting pipeline, design selection and production installed and used and manage all bring great inconvenience, specification is various, and regulation range is little to be the one drawback.Effect was better when 2, the T-shaped clip of spring connected in major diameter pipeline system, but when the following minor diameter pipeline of 80mm connects, will occur puzzled, the one, this structure can't be produced the specification of minor diameter, the 2nd, the circular arc of small dimension is less, the necessary bending of T-shaped bolt, the T-shaped bolt of bending is after loading, fatigue can appear in bending part, meeting slowly is straightened, stretching bolt has indirectly discharged the spring energy that compresses, the regulatory function of spring lost efficacy when becoming flexible appears in pipeline, and this is the second largest drawback of the T-shaped clip of spring.Particularly the clip specification of cooling system is less, can't solve the fastening problem of secondary by the T-shaped clip of spring at all.
Therefore, the cooling system that how to solve fuel power become with the leakage of less pipeline in the cold-heat exchange system pendulum in face of people one to a difficult problem.
The model utility content
For above-mentioned deficiency, technical problem to be solved in the utility model is, how to provide a kind of simple in structure, the size regulation range is large, possess fastening automatic regulation function, can be applicable to less pipeline in cooling system and the cold-heat exchange system in case the worm gear clamping hoop that possesses regulatory function that stopping leak leaks.
In order to solve the problems of the technologies described above, adopted following technological scheme in the utility model.
A kind of worm gear clamping hoop that possesses regulatory function, comprise and be bent into circular band and the hoop seat that is arranged on the band, one end of band passes movably the hoop seat and be provided with along the length direction one section wrom tooth section on this end, be provided with worm screw on the described hoop seat, worm screw have a rotation force side that is positioned at the hoop seat outside with one insert the hoop seat and with band on the wrom tooth section end of engagement of interlock mutually; It is characterized in that, a side that deviates from the wrom tooth section on the described band inner ring wall is provided with elastic structure.
In the utility model, on the basis of traditional worm gear clamping hoop, set up elastic structure at the band inner ring.When clip uses, the compacted compressive state that is of elastic structure, when pipeline deforms diameter when diminishing, elastic structure restores to the original state provides pretightening force, continues the pipeline chucking has been realized self-adjusting function, has guaranteed the sealing of pipeline junction.Because clip is worm gear clamping hoop, therefore the long enough that the wrom tooth section on the band can be done has improved the size regulation range.Being specially adapted to cooling system is connected the connection of less pipeline and locks to prevent the leakage of expanding with heat and contract with cold and causing owing to pipeline with cold-heat exchange system.
As optimization, described elastic structure integral body is crescent shape, comprises that two ends are connected to the arc spring support on the band inner ring wall, is provided with the spring that acts between the two between arc spring support and the band inner ring wall.Adopt so simple structure to make it possess larger elasticity, simultaneously, the elastic arc sheet can increase and the tube contacts area when compressing, and improves locking effect.
As further optimization, described spring is the spring sheet of arc, and the elasticity direction of spring sheet is consistent with the clip diametric(al).Have advantages of that elastic force is higher.
In sum, the utlity model has simple and compact for structurely, the advantage that the size regulation range is large possesses the fastening function of automatic adjusting, has guaranteed the sealing of pipeline junction, is specially adapted to less pipeline in cooling system and the cold-heat exchange system in case stopping leak leaks.
